For 15 Belgian and German Shepherds life was a living hell at the hands of breeders on a Yandina property until the team from Belgian Shepherd Rescue Australia came to their aid.

The appalling conditions at the Yandina breeder property.

The biggest rescue mission ever undertaken by the group of dedicated volunteers saw the last of the 11 puppies and four adults removed at the weekend, nine days after their liberation began.

BSRA founder Liz Saunders said it was the power of social media that effectively saved the lives of the maligned mutts.

"It was a tip-off from the Sunny Coast Community Board," Ms Saunders said.

The alarm first sounded by concerned neighbours soon gained traction with the Facebook group, with BSRA able to monitor the post before taking action to save the dogs.

The toughest task now is to secure donations to help treat the dogs, which are suffering from a range of injuries and ailments including bite wounds, hernias, open sores caused by their crude chains and cable tie collars, diarrhoea, dehydration and paralysis ticks among others.

"It's the worst that I've ever seen," Ms Saunders said.

"A couple of dogs had quite serious hernias and none of them (the pair with hernias) had ever seen a vet.

"One mother had a horrific injury to her neck ... the crude chain had sliced her neck open and it was pretty horrendous, we had to keep the chain on until she saw a vet."

Ms Saunders and other members were eventually able to negotiate the release of the dogs, as well as a guarantee the couple would stop their breeding business.
